The first found wp_mail is on line 2793, the again at the following:
3003, 3035, 3059, 3083, 3121, 3153, and 3351.

I'm not sure how you could have tried and tested on your site by uncommenting one line that isn't anywhere near 1501. Thanks for your help though, I've uncommented out all of them.

As far as the plugin feature request, you all have a WHMCS - Pro Sites integration (that I don't believe many people are using), where WHMCS is the billing, notifying, creation of Pro Site etc. This feature shouldn't need any votes, it should be a necessary because of the WHMCS integration. Nobody wants to receive redundant emails and when integrated, WHMCS handles everything.

Please contact the developer of the plugin and notify him of this thread and the need to have this option because of integration.

It's a nice thing to integrate these but so far none of it works as it supposed to.

I am sorry for confusion going on here. I think Nastia thought you only want to disable email notification of new receipts. If you want to disable all email notifications then you have to comment all those instances of wp_mail function at the moment.

You are right, this should be disabled or there should be toggle to disable these email notifications. I am forwarding this request to our developers for consideration.

This feature is already added to the developers' list. I have pinged our developer regarding this feature request. I can't confirm that it will be added in the next update, but it will be added eventually.

As there isn't any further development about this request, I already followed-up our internal report to get any insights, if any, from our developers. Either way, I will let you know as soon as possible.
